In these days, when attention has been so much directed towards the cultivation of the common kinds of eatable shell-fish, it is surprising that the importance of certain others for food has been hitherto almost entirely overlooked. We understand the good qualities of oysters, cockles, and a few other kinds; but some equally nutritious (which are universally eaten on the Continent) are seldom, if ever, seen in our markets, or are only used locally as food, and the proper modes of cooking them are scarcely known. I have therefore endeavoured to call attention to all the eatable species common on our coasts, and also to those which, though not found here in abundance, might be cultivated as easily as oysters, and form valuable articles of food.
